Better, the invention provides a kind of personal navigation apparatus of integrating lane bias alarm system, wherein, described image acquisition unit is built-in or is external in the camera unit of personal navigation apparatus.
Better, the invention provides a kind of personal navigation apparatus of integrating lane bias alarm system, wherein, this image identification unit is built-in or is external in the lane shift device for identifying of personal navigation apparatus.
Compared to prior art, the invention provides a kind of personal navigation apparatus of integrating lane bias alarm system, do not need the indicator signal circuit on the car is integrated into lane bias alarm system, it is the indicator signal that lane bias alarm system does not need directly to obtain vehicle, the voice signal that triggers in the time of only need obtaining the start of direction of traffic lamp, can avoid when driving is deliberately switched the track, lane bias alarm system is made false judgment, when effectively having avoided driving deliberately changing Lane, the situation that driveway identification system gives error prompting occurs.
For making purpose of the present invention, structural attitude and function thereof there are further understanding, hereby cooperate diagram to be described in detail as follows:
Description of drawings
Fig. 1 is block diagram of the present invention
Embodiment
Please refer to shown in Figure 1ly, be block diagram of the present invention.The invention provides a kind of personal navigation apparatus 10 of integrating lane bias alarm system and mainly comprise sound acquisition unit 101, storage element 102, comparison judgment unit 103 and caution unit 104.
Wherein, present direction of traffic lamp (not shown) is connected with a relay, when the driver opens indicator, triggers simultaneously this relay work, makes this indicator flicker and signal of sounding simultaneously.
The invention provides a kind of personal navigation apparatus 10 of integration lane bias alarm system, wherein, described storage element 102 triggers the voice signal that this relay sends during in order to the start of store car indicator; Described sound acquisition unit 101 triggers the voice signal that this relay sends when capturing the start of direction of traffic lamp, and in present embodiment, this sound acquisition unit 101 can be built-in or is external in microphone on this personal navigation apparatus; Described comparison judgment unit 103, it is electrically connected with this sound acquisition unit 101 and this storage element 102 respectively, and caution unit 104, and this caution unit 104 is electrically connected with this comparison judgment unit 103.
This comparison judgment unit 103 during with the direction of traffic lamp start of this sound acquisition unit 101 acquisitions the voice signal that triggers and the voice signal that is stored in this storage element 102 that reads compare judgement, and send one control signal to the caution unit 104, this caution unit 104 receives the control signal that this comparison judgment unit 103 sends, from when lane bias alarm system is judged automotive run-off-road, control this caution unit 104 and close or start.
The voice signal that triggers when this comparison judgment unit 103 is judged the direction of traffic lamp start of these sound acquisition unit 101 acquisitions is identical with the voice signal of these storage element 102 storages, drive expression at this moment deliberately at changing Lane, rather than because drive the automotive run-off-road of diverting one's attention not notice, therefore do not need to do the prompting of lane shift, at this moment, 103 of comparison judgment units send control signal, control this caution unit 104 and close.
When lane bias alarm system is judged automotive run-off-road, and this comparison judgment unit 103 judges that this sound acquisition unit 101 does not capture voice signal, then send control signal, control this caution unit 104 and send alarm signal, reminding driver automotive run-off-road, this alarm signal can be one of them of an entity cresset, a voice broadcast and a high frequency caution sound.
Again, described lane bias alarm system also comprises the image acquisition unit (not shown), this lane bias alarm system sees through the image that this image acquisition unit captures, again via the corresponding position in this pick-up image of the road interval line in this pick-up image of image identification unit identification, when correspondence position dropped on the caution zone of acquiescence, lane bias alarm system was then judged automotive run-off-road.Wherein, described image acquisition unit is built-in or is external in the camera unit of personal navigation apparatus 10 that perhaps, this image identification unit is built-in or is external in the lane shift device for identifying of personal navigation apparatus 10.
The invention provides a kind of personal navigation apparatus 10 of integrating lane bias alarm system, do not need the indicator signal circuit of vehicle is integrated into the personal navigation apparatus with driveway identification system, only need obtain to drive the voice signal that triggers when deliberately starting the start of direction of traffic lamp, make false judgment in the time of can avoiding switching the track, when effectively having avoided driving deliberately changing Lane, the situation that driveway identification system gives error prompting occurs.
The above person only is the present invention's preferred embodiment wherein, is not to limit practical range of the present invention; Be that all equalizations of doing according to the present patent application claim change and modification, be all claim of the present invention and contain.
